CARL M. OLSON AND FRANK O. HELLSTRQ 1H, 03 G-BOVE, NORTH DAKOTA,ASSIGNORS TO FRANK O. HELLSTEDM, OF GROVE, "NORTH DAKOTA.

RAILROAD-RAIL.

To all whom, it may concern Be it known that we, CARL M. OLsoN and 11mm: 0. l-lnLLs'rnoM, citizens of the United tdtates, residing at Grove,in the county of Burleigh, State of North Dakota, have invented a newand useful Railroad-Rail, of which the following is a specification.

This invention relates to the improvement of railroad rails.

.he invention has for its object to provide for the longevity of the useof rails, the same being reversible, and also provides a factor ofsafety in that the .rail is constructed of two separate component partsof metal permitting the combination and use of metal of differentdegrees of temper and hardness, the same being joined together by meansof bolts or rivets, being so constructed as to form a continuous railand wit-h that general I end in view.

A further object is to so-construct or devise the individual parts ofthe rail structure as to obtain certain advantages which shall beconducive to the aforesaid general end.

A. still further object is to carry out these ends in a simple,effective and expeditious manner.

The invention consists of certain instrumentalities and featuressubstantially as hereinafter fully disclosed and defined by the appendedclaim.

In the accompanying drawing is illustrated the preferred embodiment ofthe invention.

It will be understood that various changes and modifications can be madeas to the detailed. construction and arrangement of the parts, withinthe scope of what is claimed without departing from the spirit of theinvention.

Figure 1 is a sectional perspective view of the invention. Fig. 2 is anend elevation of the same. Figs. 3 and 4 are separate views in elevationof the primary members of the rail structure.

In carrying out the invention, there is formed a rail-member proper 1 ofapproxi mately Z-format-ion, the web-forming member 2 thereof, however,being perpendicular to the duplicate tread forming members 3 and 4,which latter are adapted to be reversed or inverted for use either asthe tread, or as the base when wear and tear make Specification ofLetters Patent.

this reversal necessary. Thus, the life of the rail is lengthened.

The duplicate treads 3 and 1 are formed each with a flat surface adaptedto constitute a base as well as the tread. The tread-portions 3 and lextend in the opposite directions beyond the web 2 to afford additionalstability and also to provide for the ready engagement therewith of thesecuring spikes. The duplicate tread members 3 and 4 also have theirinner edge-portions formed in ogee configuration, as seen at 5, thepurpose of which will presently appear. The ogee curve 5 defines a rib6, whereby the tread is thickened and reinforced and, further, theweb-portion 7 of the cooperating angle mem here 8 may be shortened, byreason of which construction certain other advantages follow, as willlater be described.

An angle member 8, which is employed for aiding in retaining therail-member 1, is formed with a knee 9 which rests upon a lateral flange9 of the tread member a, or upon acorresponding part 9 of the treadmember 3, when the rail 1 is inverted. The upper edge of the anglemember 8 engages with the upper tread-member in the resultant seat ofthe ogee-curve 5, whereby the vertical arm 7 of the angle-member 8 isthus centralized. with respect to the railtread, to aid in reinforcingthat member, where the greatest stress occurs. The angle member 8 has,it will be noted, a laterally extended lower flange 10 constituting asup-= porting base, whereby said angle member may be utilized tocompensate for less or reduced thickness of web of the steel rail, aswell as to allow of lowering or rendering lighter such steel-railmember, as is thought apparent.

The an le member 8 is connected to the web 2 of the rail-member 1 bybolts 11 passing through openings 12 in the member 8 and throughelongated openings 14: in the web 2.

What is claimed is A railwayrail of approximately Z-shaped outline,having duplicate tread-members said tread-members having theirinner-edge portions of ogee-like formation, an angle member having itsupper end received within a resultant seat of the ogee-like formation,said angle-member having a knee adapted to fit upon the base of saidrailmember, and means for securing said angleas our own, We have heretoaffixed our sigmember to sald rall, 111 such a manner as natures 1n thepresence of two Witnesses.

to lit and interlock with the inner flange of said reversibleapproximately Z-shaped rail, gfigg bo g ggs w 5 and said angle-memberand Z-shaped rail being united together and supported c0n- Witnesses:
